Bricks are a staple construction material the world over. The first bricks were made using clay and/or whatever dirt was available, forming the materials into the desired shape and size, and then drying or “baking” them in the sun.

Today, most western bricks are made from a combination of clay and shale, which is shaped and then fired at extremely high temperatures. While this process yields a durable product, it is extremely energy consumptive. As a result, innovative architects, scientists, and builders are finding sustainable ways to create the world’s building blocks.

We are going to take a look at two of the newest sustainable products to appear on the Brick Evolutionary Timeline: Better Bricks and Wool Bricks. These new products may revolutionize green design.

Better Bricks. Better Bricks were invented by Ginger Krieg Dosier, an assistant professor of architecture. They use sand, common bacteria, calcium chloride and urea to create a durable building product that is sustainably manufactured.

Wool Bricks. The name says it all; Wool Bricks are made using wool fibers and a natural polymer that is found in clay. They are the brain-children of Scottish and Spanish researchers who were concerned about the environmental impacts of brick production. Consider that the resources to produce one year’s worth of bricks creates more pollution that all of the airplanes in the world.

These non-traditional bricks can positively change the global design/build footprint.
